Revert "once: Fix panic when module unload"

This reverts commit 6815e21f which is
commit 1027b96e upstream.

The function __do_once_done() added a new parameter to handle the
problem when unloading modules with that function in it.  Android does
not support module unloading so just revert this as it breaks the kabi.
